Precedents

Tsushima was an important trade center during this period. The private trade started between Goryeo, Tsushima, Iki, and Ky?sh?, but halted during the Mongol invasions of Japan between 1274 and 1281. The Goryeosa, a history of the Goryeo dynasty, mentions that in 1274, an army of Mongol troops that included many Korean soldiers killed a great number of Japanese on the islands.

Tsushima became one of the major bases of the Wokou, Japanese pirates, also called wak?, along with the Iki and Matsuura. Due to repeated pirate raids, the Goryeo dynasty and the subsequent Joseon dynasty, at times placated the pirates by establishing trade agreements, as well as negotiating with the Muromachi shogunate and its deputy in Ky?sh?, and at times used force to neutralize the pirates. In 1389, General Pak Wi () of Goryeo attempted to clear the island of Wokou pirates, but uprisings in Korea forced him to return home.

On June 19, 1419, the recently abdicated king Taejong of Joseon sent general Yi Jongmu to an expedition to Tsushima island to clear it of the Wokou pirates, using a fleet of 227 vessels and 17,000 soldiers, known in Japanese as the ?ei Invasion. The Korean army returned to the Korean Peninsula on July 3, 1419,[2] and Korea gave up occupation of Tsushima.[3] In 1443, the Daimyo of Tsushima, S? Sadamori proposed a Gyehae treaty. The number of trade ships from Tsushima to Korea was decided by this treaty, and the S? clan monopolized the trade with Korea.[4]

Treaty terms

This treaty was signed by Joseon dynasty king Sejong the Great and the Lord of Tsushima island in 1443, and the daimy? of the So clan of Tsushima island was granted rights to conduct trade with Korea in fifty ships per year, in exchange for receiving a substantial stipend from the Korean government and aiding to stop any Japanese coastal pirate raids on Korean ports.[5][6] This Treaty was discarded by the revolt of the Sampo in 1510.
